Why does my QEMU guest mouse stop working?
I use Qemu to run multiple virtual machines. One of them is using Windows 8.1 Pro (x64) and is used for back-ups. The guest runs fine without any problems. But when I start passing through an usb-device (external hard drive) the mouse (keyboard still works fine) stops working on the vnc client. Reconnecting to the vnc-server does not work.
